Application filed March 20, 1912.

To all whom it may concern Be it known that We, JOHN Josnru CITARLEY andFREDERICK LAtirLoUcn, both subjects of the King of England, residing,respectively, at Malvern, Victoria. Australia,. and Willesden Junction,London, England, have invented certain new and useful Improvementsin-Spring Suspension for Vehicles, of whi" the following aspecification.

This invention relates to s 'iring suspension for VQl'1l(l6S forabsorbing; or reduci 2 road shocks and the like, and comprises novel andeiiicient means whereby wheels of a vehicle which are each mounted onseparate pi vets may be resiliently suspended independently of the axle,or axles, and of the usual suspension springs or other axle sup portingelements.

The object of the invention is chiefly to obviate the necessity for theuse of pueumatic tires on motor road vehicles and genorally to minimizeshock to a far greater extent than is possible by the present knownmeans for which purpose it is necessary to prevent rolling and pitchingof the vehicle when encountering obstructions by causing each wheel toact independently and at the same time control the nwvementsmf anotherwheel or wheels. The principal cause of such rolling or pitching; is dueto each pair of wheels beingrig-idly mounted on or pivoted to atransvcrs: axle so that when a wheel encounters an obstruction it notonly passes over such obstruction but isf-ansmits a tipping or rolling:motion to the vehicle owing to the transverse axle causing thecorresponding wheel on the other side to be inclined proportionately tothe wheel passing-over the obstruction.

According" to this invention the above ac tion rendered impossible andall motion imparted to a wheel passing over an ob struction isneutrali'lzct' by the shock being primarily confined to that particularwheel, which in turn transmits the shock to another wheel or wheels, theshocl: being finally entirely eliminated by lifting the vehicle bodyevenly over its entire base or superficial area, and thus i'mnsforinin;the rolling or pitching motion into a slight. undulating lifting"movement over the whole.

Broadly stated the invention consists in a pivoted 0r articulated memberor arm in or onwhich a running" or road wheel is mounted, if necessaryto have the necessary steering or turning movements in vertical orsubstantially vertical planes, Sthis lever beinp positively connected toappropriate shock absorbing and normalizingdevices and. by the latter toanother similar lever carrying another llll'll'llIlQ or road wheel, thesaid shock absorbing and normalizing devices being appropriately of thehind described in the specification of prior patent to J J. Charley N0.1.013742, granted 2nd Jzmuary 1912. The said pivot-ed member is guidedby and is capable of rocking; movements in a vertical or substantiallyvertical plane independently of a second member in 'ie'id connectionwith a suspension spring or equivalent element connecting said sec- 0ndmember to the vehicle frame or chassis or with an. axle in such amannerthat while permitting said pivotal. member to rock in a verticalplane all latter play or torsional movements and strains are eliminatedthus 'iern'iitting' the wheel to acco-nnnt'idate itself freely toobstructions which it niay encounter and transmit the shock to anotherwheel while preventing all' tendency to wabble or become unduly inclinedrelatively to the chassis.

An embodiment of the invention is rep resented in the accompanyin;drawings in which- Figure 1 is a side elevation of a road vehielochassis showing" the invention applied thereto, with the shockabsorhing' and norinalizing devices illustrated dia; 1'rannnatically. l2 is a fragmentary side elcvation of the front portion? of the chassisshowing the invention in slightly modified form. Fig. 3 is a sideelevation of the wheel carrying member and appurtenant parts and 4 is asectional plan view of'l io the two latter figures being drawn to ascale considerably enlarged relatively to Figs. l

and 2.

in said drawings, 1 represents the chassis or frame of the vehicle, 2the running whccls, and the shock absorbing and normalizing system for afull description of which latter reference directed to the aforesaidLetters Patent 1013742.

4t designates ordinary semi-elliptical laminated suspension springswhich are attached as by straps 5 to a plate 6 forming Within the hollowboss 12 is keyed a spinrt of a bracket 7 provided with a tubular ss 8 inwhich is housed one end of a transverse shaft or axle 9 extending to'theopposite side'of the-vehicle where it carries a similar bracket on thatside connected to a suspension spring. Extending from the I boss 8- aretwo arms 10 integral at their is jourhaled a hollow boss 12 forming theI fulcrum of an arm 13, a suitable linervor' shown as. interposedouter'ends with a bearing sleeve 11 in which bushing l4 being tweengthesleeve-and boss. In connection with the front or steering wheels of.t-heIjvehicle'the said arm'13 is provided on its eit- "terior with alug. 15 having a vertical perforation 16 therein forming which isjournaled the usualpintle ll' having pivoted thereon a fork 18 carryinga stub shaft 19 on which the runnin wheel is revolubly mounted tl-iesaid fork eing extended below't-he lug as shown at the left hand side ofFig.1 for connection of the usual steering rod 20 and connecting mem-'ber 21 to the vwheel on the opposite side of the vehicle.

What we claimas our invention and desire to secure by Letters Patent ofthe United States is:,-

1. In a vehicle suspension, the combination with a vehicle frame, of aplurality of supporting "members substantiallyfixed with relation tosaid frame, a member articulated at one end to each of said supportingmembers, a running wheel revolubly mounted adjacent the free end of eachof said articulatedmembers, and shock absorbing and normalizing meansand connections inter-'- mediate a pair of articulated members at eachside of the frame whereby pivotal movements of one articulated ,memberare transmitted through said shock absorbing and normalizing means toanother articulated member.

- 2. In a vehicle suspension the combination with a vehicle frame. of aplurality of supporting brackets substantially fixed with relation tosaid frame, an arm pivoted at one end to each-of said brackets to becapable of rocking movements in avertical plane, means adjacent the freeend of each armffor supporting a running wheel, a

shock absorbing and normalizing system intermediate a pair of bracketsat front and rear of the vehicle, a lever in fixed relation to saidpivoted ,arm and connections between said levers and. the shockabsorbing and normalizing system.
